I followed the advice of the Apple technical support specialist today. I had read one article which suggested that a complete clean install of Mac OS Big Sur onto my machine might fix the problem. This was on the basis that perhaps a required file had been either not copied or corrupted on my previous upgrade install from Catalina to Big Sur. So the technical specialist suggested that I perform a clean install.


So I bought myself a Samsung External USB T5 1TB SSD drive; configured it as a boot drive; installed a clean Mac OS Big Sur boot image ver 11.5.2 from the Apple App Store; and booted from there. Not a hapeth' of difference whatsoever. Safari still displays the green horizontal bars and rendering issue.


Perhaps this version of Mac OS should be called "Bug Sore"

This must have something to do with the GeForece 750M or 650m, just anything Nvidia in general?

I feel the GPU has terrible compatibility and performance issues with Big Sur (Bog Sore) in general.

I've have premiere pro and photoshop performance drops since updating from Mojave, as well as the green rectangles in safari.

C'mon Apple, I waited over a year to update to Big Sur so that all the bugs could be fixed, how is it still this bad when Monterey is on the verge of being released publicly.


I'm on a late 2013 15" MBP with 16gb, GT 750m, 2.6ghz i7.
